The last couple years we've dipped into retirement to pay for college. I know you're not supposed to do that, but it is what it is. Because of that, we've been having to make quarterly estimated tax payments. This year we're supposed to pay $3600/quarter in estimated payments. My last kid graduated in December and we will not be doing that anymore. I'm expecting to have $60K less in taxable income in 2025 than 2024. Am I required to make those $3600 payments if I know my taxable income will be much less, or is there a way to file an adjustment to them?
